Abstract

740,850. Lathe and like centres and drivers. KOSTYRKA, T. A. Aug. 4, 1953 [Aug. 4, 1952; April 4, 1953], No. 21464/53. Class 83 (3). A driving centre for machine tools, comprises a body 2, Fig. 3, in which a centre 3 is slidable axially against a spring 4, plungers 7 in bores surrounding the centre 3 engaging, at their inner ends, balls 6 in an annular recess 5. The plungers support a disc 12 retained to the body by a cap 14 and having teeth 21 engageable with the end face of a work-piece supported by the centre. Movement of each plunger is limited by a pin and slot. In fixing work between centres, the tailstock is advanced to cause centre 3 to compress spring 4 until the end face is engaged by the teeth. The movement is continued until the plungers cause the balls to engage a shoulder 19 on the centre, thereby preventing further movement of the centre. The disc 12 may be integral with the teeth, in which case several discs are provided for work of different diameters and for rotation in opposite directions, or provided with radial grooves in which separate teeth are slidable to various positions. In another arrangement, the plungers 7, Fig. 10, have teeth 25 and may be oval with teeth 25, 25<SP>1</SP>, Fig. 11, to cope with differing diameter work. The plungers may be turned through 180 degrees for rotation of the centre in the opposite direction.
